Embodiment Construction

[0046] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0047] Such as figure 2As shown, this embodiment is a method for automatically adjusting the transmission path of a video media stream, which is applied to a video sending end in a video surveillance system. The video sender in the video surveillance system can be a camera, a network hard disk video recorder NVR, or an encoder, etc.; correspondingly, the video media stream sent by the video sender is received by the video receiver, which includes a video client, or other receivers Devices for media streaming, such as decoders, NVRs, etc. In the following embodiments, a camera and a video client are taken as examples for illustration.

Abstract

The invention discloses a method and apparatus for automatically adjusting a video media stream transmission path. The method comprises the following steps: when a video sending end senses the blockage of video media streams, obtaining a source MAC address of a message from messages sent by a video receiving end, searching optional paths of the video media streams according to the source MAC address, and selecting a backup path of sending the video media streams from the searched optional paths, modifying the destination MAC address of the video media streams into the MAC address of a router equivalent to a gateway router of the video sending end in the selected backup path, and sending the video media streams to the video receiving end through the selected backup path. The blockage problem of the video media streams is solved. The apparatus disclosed by the invention comprises an address obtaining module, a path search module and a sending module. By adoption of the method and apparatus disclosed by the invention, the judgment and calculation are efficient, the accuracy is high, the feasibility is strong, the backup path of the video media streams can be changed conveniently and quickly, and no attention needs to be paid to the networking structure of an intermediate network.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a method and device for automatically adjusting the transmission path of video media streams. Background technique [0002] In a video surveillance system, in order to make the video sender (such as a camera) communicate with other network elements (such as a video management server, video client) normally through an IP network, a certain router is usually set as the gateway router of the camera. All IP data packets sent are forwarded through the gateway router, so the transmission path of the video media stream when it is sent from the camera to the video client in a certain network segment is usually a single path, such as figure 1 As shown, the transmission path of the video media stream sent from the camera to the video client is: Layer 2 switch E→router A→router B→Layer 2 switch F. Insufficient network bandwidth causes network congestion and packet loss, resulting in freezes...
